Two leading VDSL2 chip makers made progress this week with technology that's designed to pipe symmetrical (and theoretical) speeds of 100 Mbps.

Ikanos Communications debuted two new "extended reach" VDSL chipsets - the Fx 100100-4-EX and FX 100100S-4-EX - for optical network units and subscriber-side equipment. Both are designed for multi-tenant unit environments, and can enable carriers to extend the reach of full symmetric 100 Mbps service up to 80 percent, the company claimed.

Ikanos said the eight-port Fx100100-4-EX chipset is designed specifically for ONU equipment, and consumes up to 30 percent less power than the vendor's first-generation. The Fx100100S-4-EX chip features a single port DSP engine.

"The MxU market has been the sweet spot for VDSL in high-density environments in Asia, and now European and North American carriers are planning to roll it out for triple play services to their multi-dwelling subscribers," said Melissa Yocum, senior market analyst at IMS Research.

Zhone Technologies, meanwhile, said it is using VDSL2 chips from Conexant Systems inside its new line of customer premises equipment and Multi-Access Line Concentrator broadband loop carrier gear.
